 MIL-HDBK-1027/3B
Change 1, 30 June 1995
2.2.11.8 Sacrificial Cladding. Provide 19 mm thick plywood in front of a 19
mm air gap on any surfaces (baffles, wing walls, metal connectors, etc.) that
are within 10 meters of the FL to prevent backsplatter. Size panels for easy
replacement of damaged areas.
a) Canopies shall have sacrificial cladding from 1 meter behind the
FL to 4 meters forward of the FL.
b) Various reprocessed rubber products for sacrificial cladding use
are commercially available. Contact NAVFACENGCOM Code 15C.
2.2.11.9 Target Line and Mechanisms.
Components will be as follows:
a) Target line bases shall match grading with the FL. Mechanical
target support bases shall be protected from the direct line of fire. They
may be buried flush with the ground or placed behind a protective wall. Note
that a small raised earth berm at this location generates significant RC. The
complexity of the mechanism will dictate the protection requirement. See
Figure 2.2-15 for wall or trench protection of high cost target line
mechanisms.
b) Target supports can be made of steel angles and channels, PVC
pipe or wood. Do not use metal parts within 10 meters of the FL where DF
strikes are anticipated. Discharging weapons close to metal surfaces is
extremely dangerous. Present the smallest surface area that is structurally
sound to the line of fire to minimize RC. Design the target holders for easy
and inexpensive replacement. This is one area to "keep it simple." Skidable,
self-supporting 2 by 4 wood frames or 2 by 2's placed into buried PVC pipe
work well on simple ranges. Note: the full face of the target shall be
visible to the shooter. The target components are at the user's discretion,
based on his training requirements. Consult with the RSO for his needs.
Provide necessary components.
c) Turning targets and the display time are at the discretion of
the user. Commercially available, electrically motorized target carrier and
electronic scoring systems should be considered when the economics of training
warrant.
d) See Figures 2.2-16, 2.2-17, 2.2-18, and 2.2-19 for rifle butts
and targets. Rifle target frames shall be 1.2 meters by 1.8 meters high for
use to 274 meters and 1.8 meters square at greater distances.
2.2.12
Multiple Firing Lines Versus Target Lines. On Type "PB" or "FB"
ranges, in most instances, a single FL with multiple target lines will produce
the most cost effective range because of the FL canopy. An extremely advanced
target mechanism may be sufficiently more expensive than multiple canopies to
shift the advantage. On Type "O" ranges the single target line with multiple
FL's is preferred; especially on rifle ranges where butts are required.
